Engine Performance problem
2006 Pontiac GTO V8 Two Wheel Drive Automatic 48216 miles
I had an '02 Camaro SS with a 5.7 V8 and it used regular Pennzoil. I had a '05 Trans Am with a 5.7 V8 and it used regular Pennzoil. I had an '89 Corvette with a 5.7 V8 - - used regular Pennzoil. (There are more) Now I have a 6.0 V8 in my '06 GTO and I'm supposed to use Mobil 1 synthetic, the most expensive made. Question: Can I just use SuperTech (walmart) synthetic? Can I just use oil? What is this? A scam? My mechanic doesn't like me using SuperTech but when I ask him why, he just shrugs. I told him I can hear the lifters now since I put in Super Tech and the gas mileage is affected, and he says it's just my conscience. What's your take? I have mixed thoughts, but overall I think it's a scam. It is HOT here in Phx tho' and supposedly the synthetic is better for that. But I suspect the difference is negligible. Advise, John
have the same problem?
